摘要： Decision metrics used to decode wireless communication payloads are combined for successive frames to improve decoding of the later received frames. A bitwise payload difference between successive frames is encoded in the same manner the payloads are encoded. Decision metrics determined for the earlier received frame are combined with the encoded payload difference to generate adjusted decision metrics. The adjusted decision metrics are combined with decision metrics determined for the later received frame. The combined decision metrics are decoded to generate a payload for the later received frame. If the decoding is not successful the combined decision metrics are carried forward and the process is repeated based on the payload difference between the following frames.
摘要翻译：用于解码无线通信有效载荷的决策度量被组合用于连续的帧，以改进后续接收的帧的解码。连续帧之间的按位有效负载差异以有效载荷编码的相同方式进行编码。将针对较早接收到的帧确定的决策度量与经编码的有效载荷差值相组合以产生经调整的决策度量。经调整的决策度量与为稍后接收的帧确定的决策度量相结合。对组合决策度量进行解码，以生成稍后接收的帧的有效载荷。如果解码不成功，则组合决策度量被转发，并且基于以下帧之间的有效负载差重复该过程。

摘要： Methods and apparatuses are provided that include selecting reference signal (RS) or other tones to utilize in estimating a channel for decoding one or more channels. Where the RS tones are interfered by other base stations, interference cancelation can be performed over the RS tones. Since interference can vary over the tones, interference cancelation can yield RS tones of varying quality. Thus, a quality of each of the RS tones can be determined, and at least a subset of the RS tones can be selected for estimating a channel. Additionally or alternatively, the RS tones can be weighted or otherwise classified for performing channel estimation using the RS tones.
摘要翻译：提供了包括选择参考信号（RS）或其他音调以用于估计用于解码一个或多个信道的信道的方法和装置。在RS音调被其他基站干扰的情况下，可以通过RS音调进行干扰消除。由于干扰可以在音调上变化，所以干扰消除可以产生质量不同的RS音调。因此，可以确定每个RS音调的质量，并且可以选择RS音调的至少一个子集来估计频道。附加地或替代地，可以对RS音调进行加权或分类，以使用RS音调进行信道估计。

摘要： Systems and methodologies are described that facilitate adaptively communicating data to wireless devices. An access point can precode a dedicated reference signal (DRS) for transmitting to a wireless device, and the wireless device can receive the precoded DRS. The wireless device can determine the precoder by estimating a channel of the DRS and can provide channel condition feedback to the access point. The access point can create data signals including a single or a burst of data transmissions according to the feedback and can precode the data signals using the same precoder. The wireless device can additionally decode the data signals using the precoder. Moreover, the access point can cycle through precoders according to a patterned, random, pseudo-random, and/or similar sequence.

摘要： Techniques for transmitting data and resource signals (RS) are provided. According to certain aspects, an access point may determine RS resource locations related to one or more access points in a CoMP set transmitting a common reference signal (CRS), map data transmissions initially over resources other than those related to the RS resource locations, and map remaining data transmissions over resources related to the RS resource locations. According to certain aspects, a wireless device may receive a signal from access points in a coordinated multiple point (CoMP) communication set comprising a common reference signal (CRS) superimposed over data, determine CRS locations in the signal that correspond to the CRS, and decode data from the signal based at least in part on the determined CRS locations.

摘要： Incremental interference cancelation (IC) capability management and signaling is disclosed. A mobile device selects certain groups of its individual IC capabilities to deactivate in response to various operating conditions it is experiencing. The mobile device reports its currently active IC capability to a serving base station, which uses information to determine whether to modify any existing communication conditions with respect to the reporting mobile device. The base station detects and analyzes the current communication conditions with respect to the reporting mobile device in light of the mobile device's currently active IC capabilities. The base station may modify such conditions through actions such as signaling the mobile device to activate or deactivate certain other groups of IC capabilities. The base station can make other modifications such as changing the communication schedule for the mobile device, modifying the control loop for channel quality indicator (CQI) reporting, and the like.

摘要： Techniques for estimating and reporting channel quality indicator (CQI) are disclosed. Neighboring base stations may cause strong interference to one another and may be allocated different resources, e.g., different subframes. A UE may observe different levels of interference on different resources. In an aspect, the UE may determine a CQI for resources allocated to a base station and having reduced or no interference from at least one interfering base station. In another aspect, the UE may determine multiple CQI for resources of different types and associated with different interference levels. For example, the UE may determine a first CQI based on at least one first subframe allocated to the base station and having reduced or no interference from the interfering base station(s). The UE may determine a second CQI based on at least one second subframe allocated to the interfering base station(s).
